add 'action.auto_create_index: false' to elasticsearch configuration

[jalogisch]

I can notice in the community that Elasticsearch is not always on the fastest machine and the index and deflector creation is slower - so that data is ingested before the indices and aliases are given.

To avoid auto-creation and having the deflector as alias we should make this default (as we already place that into the documentation step-by-step guides.

action.auto_create_index: false
